Day 5 Task: Advanced Linux Shell Scripting for DevOps Engineers with User management

What do you think if you have to create 90 directories at a time, how will create it one by one or using script or command.

Here Linux shell scripting comes into the picture. There are two different ways, we can create directories at a time using command and script.

Method 1 using command:

Method 2 using scripting:

Method 2 is called command line argument method while the time command execution we can give the input and execute it.

1. Create a Script to backup all your work done till now.

   bash
   #!/bin/bash

   backup_dir="/path/to/backup/directory"
   timestamp=$(date +"%Y%m%d_%H%M%S")

   tar -czvf "$backup_dir/backup_$timestamp.tar.gz" /path/to/source/directory
   ```

2. User Management:

   Dive into the world of user management in Linux. Users are the backbone of operations. Create two users and display their usernames:

   ```bash
   #!/bin/bash

   user1="user1"
   user2="user2"

   # Create user1
   sudo useradd -m -s /bin/bash "$user1"

   # Create user2
   sudo useradd -m -s /bin/bash "$user2"

   echo "Users created successfully: $user1, $user2"
